The c.980A>G (p.Y327C) alteration is located in exon 3 (coding exon 3) of the XKR7 gene. This alteration results from a A to G substitution at nucleotide position 980, causing the tyrosine (Y) at amino acid position 327 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
